UnicodeDecodeError: ‘utf-8‘ codec can‘t decode byte 0xb4 in position 6: invalid start byte（已解决）

自制csv文件，开头含中文。

在调用pandas.read_csv()时：

df = pandas.read_csv(csv)

打印df，遇到报错：

 按照有人的建议，改为：

df = pandas.read_csv(csv, encoding='ISO-8859-1')

或者

df = pandas.read_csv(csv, encoding='latin1')

可以打印了，但是乱码。

中文的事情还得中文解决，最后改为：

df = pandas.read_csv(csv, encoding='gb18030')

没问题了。
